The flat is very well located, it is less than a 7 minute walk from several underground stations, which means moving around the city is very easy. Also, within a 20-minute walk you can get to pretty much anywhere relevant in central Madrid.
Rafael and Rosa are great hosts and reply to any query within minutes, also very accommodating should you need anything specific. You have your own keys and you can pretty much make yourself at home within a few seconds after arrival.
The bed is a bit tight for 2, but it works. It also has a nice sofa-bed in the living/dining area. It has a full kitchen and a washing machine if needed. The bathroom is well equipped with a great shower (no bath). It is nice and spacious as well.
The setup is like a typical Spanish flat so if you're looking to feel at home, this is your place. Plenty of bars, restaurants, coffee shops and places to go within a few minute walks. Also a supermarket 2 blocks away.
They offer good speed wifi and a few really nice touches, like a welcome note written on a board, a couple of juices and soft drinks in the fridge and coffee capsules for the coffee machine.
Everything is spanking clean and it gives you a lot of confidence in having everything there.
I will definitely stay here next time I go to Madrid. The only reason I won't is if they are busy those days and I highly recommend anyone wanting to experience Madrid like a local to stay there. Thank you Rosa and Rafael!
