Even though I haven't met Roberto in person we were contacting each other. Keeping in touch with him was smooth and I am really satisfied when it comes to our contact. A friend of him who took care of the check in/out procedures was absolutely friendly and helpful.
The apartment was clean and really nice, equipped with all required amenities. Located between 2 metro stops of line A (about 10 mins away from each). Few grocery shops and one bigger supermarket in a walkable distance.
The flat is perfect for one person, for a short as well as long-term residence. Just please, keep in your mind that only person can be accommodated in that lovely apartment.
After the initial misunderstanding, Roberto had presented a very cooperative approach and helped to solve the problem that was entirely created by me.
To sum up: Roberto is a great host. The flat is lovely, perfect for people who prefer silence of the residential area, independence and standard above the location in a walkable distance from the main tourist attractions.
