Sergio's appartment is perfect for a small stay. It's well located, & spacious. The matresses are quite soft (to take into consideration if you prefer harder ones). The apartment is very well equiped and the building is calm. By the pictures we thought it would be more modern and luminous than its actually is, and were a bit disappointed in that regard.
Also, the bedrooms give on the street so its quite noisy at night (people & cars).
Sergio was reactive and welcomed us well.
