The apartment itself was lovely, spotlessly clean, fresh and modern with great kitchen facilities.
Unfortunately for me, I had the bedroom closest to the street, and the noise espespecially on Friday and Saturday was too loud to be able to sleep, even with earplugs in. I ended up moving my mattress across to the back bedroom, where you can shut the doors and block the noise out. Gorka has said he will address this for future guests.
Just be aware the apartment is in a handy location close to the old town, but on the edge of an area where we were warned by locals has lots of thieves. We felt safe enough, we didn't stay out late. The apartment is secure.
