We (family with 3 kids) had a great time in Lisbon. The big and nicely done up apartment is located in a safe neighbourhood. Close to the apartment is a grocery store with fresh bread. The condominium ist new (2015) and high standard. At the entrance to the condomnium, there is a nice security gard.
The kids loved the big TV with a lot of channels (also 2 in german) and the AppleTV-Box (for AirPlay).
We enjoyed a lot the swimming pool, which was still pretty warm (end of september). Most of the time, there were no other people at the pool. There is also a whirlpool and showers and toilets next to the pool area.
A taxi to the center of Lisbon costs less than 10 Euros. There is also a tram from Belém to Lisbon.
Laima is a very friendly an helpful host. Everything was as promised. We can absolutely recommend a stay in Laimas apartment. If we come back to Lisbon once, we will rent again this apartment.
