Overall we had a great stay, but we do need to mention one negative: we didn't realize until after we checked in, but there was only 1 roll of toilet paper in the bathroom and nothing in the kitchen (not even basics like salt, pepper, or paper towels). For two adults staying for an entire week, I think it's fair to expect those basics...
That small inconvenience aside, we had an absolutely fantastic time at Marta and Paul's apartment. It's exactly how it appears in the pictures (clean, spacious, and comfortable for two) and located in a great area for people looking to tour the city.
We would definitely recommend staying here. Just make sure you ask for extra TP ;)
