Leonardo was a perfect host, even though I did not have an opportunity to meet him in person. He arrange the check-in at the best time possible for me and there was a bottle of cava and biscuits waiting for me at the flat. I also received a great fruit basket as a gift for the Russian Christmas. In other words, he was a very attentive host.
The flat was really clean and well-equipped. The heating worked well, so it was always a comfortable temperature.
The location is extremely convenient. The Royal Palace is just round the corner and it is a walking distance to all the main attractions. There is a number of supermarkets and bars and restaurants nearby.
Everything was great, but personally I found the absence of windows in the bedroom a bit of an issue. But it is just my quirk, no fault of Leo's.
