I enjoyed my time in Lisbon and the stay in this appartment.
It is located in a rather central part of town, making it possible to walk almost everywhere. But it is still away from the big hustle and bustle, so it is not too noisy.
Sometimes you could hear the other guests, but that was not too bad either. It obviously depends on who you stay with.
My room was small but cosy and offered everything you need. The newly installed air conditioning is really great.
The kitchen is well equipped for cooking and eating. A lot of Mini Markets in the same street make it easy to supply yourself with food etc..
I personally never had a Problem regarding the shared bathrooms, there was always at least one available to use.
The communication during the stay was nice, prompt and helpful.
