We stayed for 2 weeks at Paco's apartment and had a wonderful stay.
The place is really beautiful, it has a lot of vibe (you can tell it's his own house and not a rental apartment), and it has everything you could need, including fast Internet. Having a terrace like the one in Paco's apartment is also a luxury.
The flat is well located, not in the center, but in a nice residential neighborhood no too far away from all the monuments and with good connections both by metro and bus. Also, there are plenty of good restaurants in the area, a great gelateria right in front of the building and several supermarkets.
Paco was always fast to respond to our messages and questions, and his mother waited for us to do the check-in until 1:00 AM because our flight got changed and even prepared us some snacks in case we were hungry ❤
Would come back. Recommended!
