I have stayed here before (April 2023) however forgot to give feedback. I will do a review for both here instead. The studio's are great, with most things that you need provided. The towels are a little on the small side though, so if you must have a bath sheet sized towel, maybe bring one yourself.
The room I stayed in earlier faced onto the main road, which has buses going along it, so is noisier than the ones at the back, so if road noise bothers you, either request a room at the back or book somewhere else. It was quiet over night however and the rooms were very quiet otherwise. The outside noise is likely to be not such a problem in colder weather. There is no air conditioning, however there a fans.
The check in hours are limited and this is worth knowing if you are planning to arrive late as the reception will be closed. They also charge a 100 Euro deposit, which is returned at the end of your stay.
I found the staff very friendly and helpful.
