We had a nice stay at Ana's flat although a few details could have been better.
PROs : location is great, walking distance from Sagrada familia, old town etc. the flat is clean and spacious, the beds were very comfortable, the hair drier is very good (important for women!). Also the terrace is great ! it is well exposed and very big. even in the winter we could enjoy it! Ana offered us a bottle of sparkling wine, chocolate and 2 bottles of water upon our arrival which was very nice.
CONs : the heating system is not efficient. Only 2 radiators for the whole flat, it took us more than 24hours to get a decent temperature. The kitchen equipment was a bit disappointing : only 6 plates / forks / knives / glasses and only 5 mugs, the Kettle was leaking and the juicer was not working. Also toilet paper was not sufficient for 6 people and 4 days. the appartment is pretty noisy because all the water pipes of the building pass by the windows and make water noise.
