It's a nice place but with quite a few things that didn't work out or broke during our two-month stay. For example, the apartment was dirty when we arrived, internet didn't work for three weeks, the tube under the sink broke, and the water boiler malfunctioned. All of these things took a while to get fixed. Both beds were a little too small for a couple. The apartment is great for two people and very close to a metro station in a quiet neighbourhood, but a bit more investment is needed to make things last.
Something to note: we actually never met Alberto because his sister is charge of the apartment. This was not a problem though.
