We stayed here for over 2 months, for a long term stay. Internet is reliable and good.
The apartment is mainly functional, and when we had issues Helena and her husband were very responsive and quick to resolve.
The apartment is on the top floor , no elevator, so after a while it gets to you to carry things up and down, especially if you have a heavy luggage. The Apartment is spacious, bright and in a quiet residential neighborhood and you never hear of anyone at night.
It is close to main subway and other main avenues to get by and under 10 euro Uber to the airport.
