We stayed at the birdhouse in the middle of February and were allocated in a private room with our own toilet and bathroom.
Negative: The room was extremely cold when we arrived (16°C). This sadly couldn't be fixed with the heating system in the room and was a thorn in the eye during ouor whole visit. The toilet was especially cold, I hope the host will do something against that. Furthermore was the communication a bit difficult. The host only answers between 10a.m. and 1p.m., which can be a little bit annoying, if you need something urgently. And the check-in starts at 1p.m. which can be late if you arrive in the morning.
Positive: The location of the birdhouse is excellent. Shops, busses and the Valenbisi system (public bike rent) can be reached in ~1 minute, the Park Turia in 7 minutes by foot. The accomodation was clean, it was looked after every day and the garbage was removed every day as well. It is great for meeting other people as there are many separate rooms with a shared kitchen and living room. Great for socialising. The check-in and check-out were very easy altough the time for check-in wasn't the best, as previously mentioned.
Conclusion: Recommended especially in warmer months, great for meeting other tourists.
