We stayed in Carmelo's flat for a long weekend in May. Carmelo was a great host, he met us at the apartment, gave us lots of information and spent time making sure we had everything we needed (maps, wifi, local info etc)
The apartment is just like the photo's - no surprises! It was clean, functional and the perfect size for a couple. I would definitely recommend to friends/family.
The real selling point for Carmelo's apartment is the location! It couldn't be better, we never took the metro, you really can walk everywhere. Plus Plaza del dos de Mayo is great! We were there over a bank holiday weekend and the square was packed full of people having a street party. There are a lot of coffee shops/restaurants/bars all within a few minutes walk. It's a really nice, lively area.

Overall it was a great stay, I have no faults whatsoever.

Thank you Carmelo :)
