My wife and I stayed here for a few days and enjoyed it very much. The flat is true to the pictures. The kitchen was well equipped with pots and tools for cooking. The wifi was stable and fast enough for streaming or video calls.
The location was great for us. It is in the middle of the pedestrian area, and a short walk to many important sights. Despite this, because the flat faces an interior courtyard, it did not have any street noise (there is a bit of noise in the small bedroom from the kitchen of the restaurant below when they are prepping food).
A couple things to be aware of: we like to sleep cooler than the AC was set to, but there was a fan which helped. Also, as the pictures show, there is no wall separating the main bedroom from the rest of the space. The shelf acts as a screen but doesn't block noise or light.
The host was quick to respond to our questions. She couldn't meet us when we arrived (we got the key from a keybox) but she came by the next morning to say hello and make sure we had everything we needed.
This is a great option for 1-2 people or a couple + small kids.
