Small and quirky apartment on fifth floor with very steep stairs, so not ideal for people with big luggage or difficulty walking. However the amazing view makes it worth it.
The central location makes it a great place to stay - 5 minutes to the metro, 10 to the train station. However most attractions are within walking distance, so public transport isn't very necessary.
Note that the local residents may be quite loud but for us it wasn't disruptive at night.
Luisa was very quick to respond and helped us with any problems.
Overall, I'd reccomend staying here. :)
