Nice, clean apartment in a very good spot of Madrid city center, if you look for the vibe of Lavapies neighborhood (that is not for everyones's taste... but is one of the coolest places of Madrid. If you look for a colorful, young, multicultural, vibrant place in the old city, this is perfect.) Madrid center can be noisy, but the apartment has good windows and is well insulated, i slept without problems.
Photos describe quite good the apartment. Decoration is nice, good light from 2 tall windows to the exterior, is not super big, but is not small, have high ceilings and feels open and has a good size for being in the old city, where apartments can be super small.
Bathroom is good compared to what you can find in other apartments in the center. You can use it and shower without problems, is a small but cleverly done, new and very usable bathroom.
Perfect for a person or a couple, even for a long stay, the kitchen is ok to cook, you can move without problems... have a washing machine... i could live there for months without problems.
A big open till late carrefour mall close to the apartment, plaza de Lavapies with metro station next to the apartment street...
One of the apartments in my list to rent again if i go to Madrid.
An advice just for people that are not used to the south of Europe... The neighborhood and Madrid in general is super safe, but for foreigns can look a bit shocking sometimes. A lot of people in the street with very different backgrounds and etnias, nightlife, old buildings and streets, Madrid can be noisy and look dirty sometimes... Relax and enjoy the difference.
