This apartment was ideally situated for us. Away from the hustle of the Ramblas - but easy to get there if we wanted to. Nice local eating places. 20 minute or less walk to most of the Gaudi things we wanted to see.
Carlos was helpful - but we were fairly self sufficient throughout.
We used the main bedroom that had air conditioning - and the lounge has aircon. We didn't use the 2nd bedroom but it would not have been good to stay in whilst we were there as it was very hot.
It was ideal for us and we would highly recommend it.
