The apartment is very cute, a bit smaller than it looks in the pictures. It is rather quiet, although if you are a light sleeper you might be woken by the sound of planes landing. Susana (Miguel's friend) was very hepful and responsive to our inquiries.
The neighbourhood is exactly as described, the Mercado is 5 minutes away and the tram stop is around the corner. The only problem is that the location is a bit away from the main points of interest and public transport is unreliable. Sometimes we waited for the tram up to 20 minutes. There is an info display at the stop (very few stops have them), but that is completely unreliable. Same thing when going back from the centre. Moreover, the stop next to the apartment is no longer served after 10pm, when the tram 28 route ends one stop further down the line, so you have to walk (not far). Luckily, Uber is cheap and reliable.
