It is fine house with enough room to accommodate two couples. It is really near station Oriente, so every other part of Lisbon can be reached with ease.
What we mind about house is poor insulation and no air condition, however climate of Lisbon is such that house can be cool down very fast during the evening so that can be managed. Ceilings are lower than standard one and bathroom has no windows while ventilation shaft and fan are kinda small, so showering can get really steamy and hot.
In general, it is fine, acceptable accommodation. For same amount of money we had much better accommodation, so that is the reason why we want grade this one with 5 stars. It is not deal breaker, but we had better :)
