Sebastian's place is amazing! It's a very well run airbnb with self-check in, spacious rooms, excellent bathrooms and amenities in the flat. We enjoyed our stay immensely, and Sebastian was very communicative and responsive, even letting us do laundry in the building. The main bedroom is slightly noisy due to being street-facing, but we had no issues sleeping. It can get hot but thankfully a fan is provided. The location is excellent, 5-10 minutes from the best of Roma Norte. Overall, we really enjoyed our stay, and would stay here again.
