We stayed 2 nights in Marias Apartment during Semana Santa and had overall a good time. The communication was very good, the check-in and check-out worked without any problems. Also the location is great as its very close to all major sights but still gives you kind of a "local" feeling as its situated in a less touristy neighborhood. The apartment is quite spacious for 2 people and pretty modern. Unfortunately it was no the cleanest place we stayed at with some mold in the bathroom. It can also get a little bit noisy as the windows don't really protect from noises on the streets. On the other hand you have a great view with a lot of sunlight coming into all rooms!
