The place was bigger than I expected and the photos don't really do the place justice. It is a little on the noisier side - cars drive by quite often on the street, people use the buzzer to access the main door (it's right next to the apartment) and you can hear footsteps from the apartment above. However noise tends to die down by 11.30 p.m.; I'm a sensitive sleeper and had no problem falling asleep. I would suggest paying a bit more for a first floor apartment away from the main door if you can.
It's about a 10-15 minute walk to most places. Google maps on your phone works just fine.
The place comes with some thoughtful touches like a washing machine, kitchenette, with washing powder and detergent included. They also provide some great tips on places to eat - I ate at two of the suggestions and was delighted with the food. Especially the oldest tapas bar in Spain - forget its name.
The woman who checked me in, Dunia, was absolutely lovely and explained the apartment thoroughly. She was kind enough to let me check in an hour early.
There was a bit of a problem when I turned on the fan and that triggered a blackout. Fortunately they very promptly fixed the problem; problems are to be expected at times, but how staff resolve it is key. Five stars for their approach!
