Just perfect!
We were met by a lovely gent on behalf on Maria and Oscar who showed us the studio and went over a map of the city with us, to give us our bearings.
The studio is fantastic. Modern, spacious, and spotlessly clean with everything you could need for a short break. It also has a huge comfy bed.
Location is ideal. It's in the heart of the city, so not really far from anything and just a few minutes walk from a choice of metro stations. There are plenty of cafes and bars on the doorstep and a bakery on the corner if you like pastries for breakfast.
I would definitely recommend Maria and Oscar's place and hope to return for another visit soon.
