The location of this apartment is very convenient. It is less than a ten minute walk to Las Ramblas, and 5 minutes to the nearest tube (if that). It is near lots of bars and restaurants, and a few minutes walk from the Barcelo Raval which has a 360 view of the city.
The room is basic, but nice. The bed is very comfortable and there are all the basic amenities one may require. It is worth noting that the air conditioning is based in the living room, and not the bedroom, so it can get quite warm.
The wifi is very good and we had no issues with it.
It is also worth noting that because of the great location, there is quite a bit of noise during the day and night. People did hang around outside, and there was a lot of noise from dogs barking.
The host Jonathan, is very friendly, and does also share the apartment. He does not speak any English, but we were checked in by an English speaking relative, and Jonathan called him if there were any translation issues between us.
I would highly recommend this place to stay, just bring your ear plugs and a translation book!
