I stayed for 5 nights in Sep 2019.
Pros:
The neighbourhood (Malasana) is very central and lively. The hotel is a short walk from Tribunal metro station. The hotel is very simple - there are 20 rooms, one floor up from ground level. Service and cleanliness were also OK. The shower design was nice in that the shower head is mounted directly overhead. Having a kettle to boil water in the room was a nice touch, as were the safe and fridge.
Cons:
The A/C unit in the room made drippy water noises.
The sink in the washroom was a bit too shallow, making it easy for water to splash onto the counter.
It would have been nice to have a bit more counter space around the sink.
The bed is a bit on the stiff side.
The neighbourhood, while lively, may be a bit too noisy for some - there are people out on the streets until well after midnight, which may be a problem if you like to sleep early.
