My wife and I as well as 5 other family members went to Barcelona for a week. The apartment was great, VERY clean, FANTASTIC location, and everything we needed. You can walk to the old quarter and the metro is only a one-minute walk away. There are a number of restaurants, mini-marts, and larger supermarkets all within walking distance. Mai provided a notebook with info including a list of restaurants in the area which we could walk to. There were a couple umbrellas by the door as well. The place is very bright and well lit. The dining area next to the kitchen seats up to 8 people though it's not immediately obvious in the pics. Mai was very responsive to my questions and quite helpful when we checked in. There's a small safe in a kitchen cabinet. There's a flat-screen TV in each of the 4 bedrooms.
There are two things to consider when looking at the apartment. First, there are high ceilings in most buildings in Barcelona and the '2nd floor' would be the 3rd floor by US conventions. As a result, there's a lot of of steps from the street level to the apartment, so if you have trouble with stairs then this might not be for you. There are handrails and several landings on the way though, and the stairs are lit if you press a switch on each floor in the hallway. The other consideration is there's really no 'living room'. In the hallway to the largest bedroom there are a couple wide chairs, but we found we sat in the dining area most of the time. Neither of these items would prevent me from renting this apartment again.
