Spacious, clean, well equipped, nicely located. We had a lovely stay. There are some great restaurants around but the bedrooms are away from the street so we had no problems with noise. A great base for exploring a lovely city. Communication with the host was very quick and easy and they gave us lots of helpful advice.
Two things that would have improved the stay. First, the bolt on the door was basically unusable so it was impossible to properly secure the apartment.
Second, in spite of multiple confirmations, the cot we were given on the first night was broken and we felt it wasn't safe for our daughter to use at her current age and mobility. The hosts had a replacement one fous the next day which was perfect, but we didn't have a place for our baby to sleep on the first night, which is obviously less than ideal. They did everything they could to get it sorted but given the importance of having a cot I would have liked them to check ahead of time that the one try had wasn't broken.
If it wasn't for that, I'd say top notch, and given their general positive attitude I expect not a mistake that'll happen again soon.
