As an airbnb host as well, I think that Joanna's place is amazing. The apartment is super well located, everything is very close, we just walked. The house is very nice, the terrace is charming. Inside you can find everything you need, basic kitchen stuffs, sugar, oil etc. The two bedrooms/ bathrooms conception is very useful when you are 4-6 persons.
Madrid is a very special place. Everybody is kind, smiley and helpful. You can fill the city, you can be one of the citizens. Joanna the owner, Joanna the co-host, Jose Manuel the doorman helped us to fill ourselves like home.
In tha house there is a small bar called Aviseu, which looks like a hole in the wall but has a sizeable dining room upstairs and serves extremely tasty food. The owner, the stuff is incredible friendly, it is a must to visit them! The buliding's street is planty with mini shops where you can find everything. Don't forget to visit a normal market in the evening, in special on the weekends, the locals are partying inside and the atmosphere is super cool.
We want to go back in the near future! :)
