The flat is in a really good location, plenty of attractions can reach by foot, also bus and metro stop is just few mins away. Quiet and polite neighbourhood.
Flat is clean and tidy and it has enough space for 3-4 people.
Tip showering: save hot water, because for third person may be too cold...
David as a host was just perfect! It was easy to communicate with him and he was offering all help which we needed. It was not a problem for him to make check-in late and even after that he was helping us to find a place to eat.
So, conclusion is that i would stay in this apartment next time and will reccomend it for my friends who will be going to Barcelona!
