We had a great stay at Vincent's apartment, and the host himelf was very nice and helpful (he gave us useful tips, suggested things to do near the house and provided us with a long list of restaurants, like a true tourist guide!). The kitchen had all the necessary equipment, and was recently renovated. The space is perfect for two, but could also fit four people, since there are two bedrooms. It is exactly as it looks in the pictures, warm and cosy. It's not very bright, as its windows see to an "atrium" with other buildings around.
For us, the best part of staying there was the neighbourhood. In 2 minutes walk, you cat get to a street full of really nice (and some of them traditional) Tapas bars and spend your evening there, which was great because after a long day of walking and sightseeing, we didn't always have the energy to go anywhere far again, at night.
Also, the center of the city is a pleasant 15 mins walk, or one-stop-ride with the metro.
All and all, we absolutely recommend Vincent's apartment. Thank you for everything, Vincent!
