We had a great stay at Josep's place. While he was out of town during our visit, the check-in was seamless. Josep communicated well with us and was very responsive when we had questions. The private written guide we received was also helpful.
The place has a great location and it is at the top of an old building. We loved the character of the place. The unit was clean and in good working condition. The doorman was also very friendly. Outside the building there is a small convenience store, perfect for the small buys (snacks, drinks, etc).
Like any old place, expect some issues. The unique layout (u-shaped with bedrooms upfront and baths and kitchen in the back) was not a big issue. Bedrooms are small and cramped. The small bath is really small and the big bath could use some remodeling. It's hard to see this from the listing pictures. These are all small things that may matter the longer you stay or the more you pay.
Overall we enjoyed our stay, would recommend and repeat.
