Gio is a great guest : he took care of waiting for me during the check-in which is always a nice attention !
He also gave me the contact of the cleaning lady which was really nice from him (especially as I was staying a month).
The flat is really close to the plaza de la Merced, so it's just perfect to explore the city center.
There are 3 supermarkets around and 2 fitness centers so it's really easy to live there without a car.
I loved the fact that there was everything you can need in the kitchen and the bathroom (micro wave oven, laundry machine, ...).
The fan in the room is also pretty useful.
The wifi works well so you can work easily from there,
The only problem I had was the noise in from the room : there was some workers working from 8 to 16H from Monday to Friday and they were pretty noisy. But if you're visiting during the day you'll not have any problem. It was just a problem for me cuz I was working during the same hours.
