The location of the flat is amazing, since the metro and the train stations are very close. Sants is an authentic and friendly area to live in.
The flat itself is lovely. The bathroom and the kitchen are well equipped and the bedrooms are simple but offer everything one needs.
Moreover the communication with the host is reliable and he is very helpful.
All in all I would definitely recommend the flat - especially for a longer stay, because you can really feel at home.
