Heinävaara's sauna facility and Architechture Guild´s cottage are no longer included in the lap tours

Heinävaara's sauna and cabinet space will no longer be booked, and the sauna facility will be removed from the Tila-system. In accordance with its intended use, the premises will be used by residents on November 1, 2023.

Architechture Guild´s cottage will be removed from the Tila calendar by the end of the year. Reservations for the fall season can still be made at Tila for the time being, but for the spring season starting on January 8, 2024, reservations will no longer be made through Tila. AK's maja is therefore no longer included in the pre-booking rounds of facilities for spring 2024.

In the future, the lodge managed by the Architektuuriklub's Lodge Foundation will be rented directly through the lodge foundation. Information about the new reservation system will be updated on Arkkitehtikilta's website. Reservations already made in the Tila calendar remain valid and the keys can be picked up normally from AYY's service office.

How to make a reservation in TILA-calendar

Please read these instructions carefully before making a reservation.

All reservations are made in TILA-calendar by logging in with Aalto e-mail address and password. The reservations are always made for personal use or for an association if the person has a right to represent the association. Any misuse can lead to sanctions.

A reservation can be made by opening the calendar view and choosing the facility and date. If the facility is free, a reservation can be made by clicking the box under the date. After this the reservation information has to be filled and rental terms accepted. The reservation goes through after "add"-option is clicked. After this the reservation will be processed by AYY's services office. If you want to cancel the reservation after this, it has to be done 14 days prior (2 days prior for the van reservations) to the reservation date by deleting the reservation or informing the services office about the cancellation. An uncancelled and unused reservation will be charged according to the price list, and it's not possible to get a refund after the invoice is sent.

If you want to see and change your notification settings regarding your reservations (for example a confirmation for a confirmed reservation, a reminder of an upcoming reservation) you can make changes in your personal information page by changing your notification settings.

If you have questions or uncertainties about it, contact the service point (

Please note that there are currently problems with rental prices. The correct prices are updated manually by AYY when confirming the reservation or before the invoice is sent. The prices for AYY's rental facilities can be found here: Price list for AYY's rental facilities


AYY reserves all rights to changes.

A code lock in rental facilities

Electronic code locks have been installed in most of AYY's rental facilities. If the reservation has been made in TILA-system, the access code can be activated when the reservation starts. If the code lock has been installed in the facility, you can find the information on our website: AYY's rental facilities

In some facilities the key still needs to be picked up from AYY's office. Also if the person who has made the reservation doesn't have access to TILA-system, the key must be picked up from our office.

If you have any questions regarding this then you can always contact us:

Sauna facilities

Most AYY´s saunas hava an electric stove you can turn on by pressing the switch in the sauna facility.

The switch must be pressed for a few seconds until a red light above the button lights up.

The exception to this is the small side of the Rantasauna, which has a wood stove.

You can heat up the sauna during the times listed below. It is not possible to turn the heat up earlier, even if you take extra hours to the beginning of your facility reservation.

These are the times when you can heat up the sauna:

  • 15-22 Otaranta rooftop sauna, Jmeräntaipalee rooftop sauna, in Ossinsauna, Sievo Sauna and Vaasankatu sauna.
  • 15-01 Gorsu
  • 12-03 the big side of Rantasauna and OK20 sauna. Note! The maximum heating time of the sauna is 8 hours. If the sauna is set to heat at 12 o'clock, it will automatically turn off at 8 p.m. It is not possible to extend the heating time. The sauna will automatically turn off at 03:00 at the latest, regardless of the heating start time.



AYY has paid more attention to the accessibility and reachability of rental facilities. Some of the facilities are nearly accessible, and we also now provide more information on accessible facilities in advance. These changes make the facilities more accessible to all users. We want to take equality into account in our operations. More information can be found from Accessibility summary and the pages of each facility in our website.
