Maria Elena is a very kind host, communication was very fluid and we had no problems for checking in. Location is perfect if you want a quiet residential area but at the same time with plenty of shops of every kind, and extremely well connected with the city centre through 3 metro lines and several buses.
The apartment is ok, we had all the amenities we needed and also space to store our stuff. The room has a private bathroom -not ensuite, but for private use- and is part of the host's flat, which is a nice thing from my point of view, meaning it is not one of several rooms to be rented to several guests and no host on site, as I may be the trend in the past year. Elena's room is Airbnb at its essence, at that's good.
The only thing I could put my finger on is the mattress: 180cm x 140cm makes it suitable for one person but uncomfortable for a couple. Apart from that, Elena's room is good value for money.
Happy travelling!
