The flat looks like the pictures, and the location is really nice, is a mostly pedestrian area (so be warned people coming with cars).
Besides being all good with the flat in looks and amenities in general, there are a few important quirks you might want to know about.
The hot water seems to be linked between different apartments, when we were showing the water would turn cold when some other apartment was using the water too.
Even when the location is really quiet, the flat wasn't so, you can hear what's going on with your neighbors, specially from the flat above.
Also, the WiFi didn't work properly, in the bedroom it was very hard to get a connection at all, in the rest of the flat it performed poorly. I mentioned this to the host and they said they were going to fix it though (but it didn't happen during our stay).
Also, we wrote in Spanish and the host replied in English, so if you are a Spanish only speaker and this is important to you, you might want to message the host first (maybe they were just used to reply to guests in English).
