The location is excellent, close to bars, restaurants and within walking distance of buses and the metro. The downside is the level of the noise - the street is small and full of tall buildings, and the balcony door is not really soundproof. If you're light sleeper, you might have trouble.
The flat is spacious, we were provided with clean towels and bedding - although the bed cover was a bit dirty. The checkin process was done via whatsapp, we received instructions on how to retrieve and drop the key at checkout, so we never met the owners or the person managing the flat.
There's room for improvement, such as providing bed-side tables or shelving in the shower, but overall we had a pleasant stay in the flat.
