Lovely, compact apartment in a great location. Right beside Museo Reina Sofia and minutes from Atocha metro. Calle Santa Isabel has loads of bars and a great market at the top.
The apartment itself was clean, fresh and comfortable. It's compact but the space is well used. Toñi left a map and umbrella for us to use.
Toñi was very helpful communicative. She was at work when we arrived so we had to go there to collect keys, but she sent many pictures and directions so we could easily find the apartment.
The only negative I have is the noise from the neighbours - particularly from the apartment above, including when they got in at 5am. You can hear people in the corridor and in the neighbouring apartments but the neighbours upstairs were partying at all hours and dragging things across the floor.
However overall I'd highly recommend this apartment. It's a fabulous location, lots nearby and an easy stroll into the centre.
