We have stayed at this hotel several times and the location is great. It is on a small narrow and quiet street. It is a short walk to Charles bridge and pretty close to the castle. The rooms are charming and the interior is well done. The staff are very friendly and they serve a nice breakfast. You can have drinks in there bar area which is small but very nice. They have indoor garage parking which is nice since the off street parking is impossible and it is better to have the secured parking.

A very nice high quality small hotel that we will continue to use on our trips to Prague.

Booked this hotel on Venere.com following good reviews, and we didn't regret. The room was spacious, clean, comfortable and nice spacious bathroom. Location is brilliant, right next to town and close to the castle, also near all the embassies. Breakfast included was ok too without being amazing. And you get free Wifi at reception (for the geeks). The people are reception were not the most smiling people but they did their job properly so can't complain.
Would definitely recommend it if you plan a nice romantic week end.
Oh an restaurant wise, we visited Chez Marcel following reviews, personnally I wouldn't recommend it unless you're after a french atmosphere in a czeck town (and the meals were nothing amazing for a good french price).... try Olympia instead near the bridge next to Charles's bridge...its listed on the michelin guide, the food is simply tasty and affordable in a fantastic place...cant go wrong there! (and cheap beer too ;-)

Excelent Old house with new interior design. Rooms and bathrooms very large! good breackfast . The distric is for to dream. embassys district, very close to castle. Internet free in lobbie.

We couldn't have been happier with Constans Hotel. Being located so centrally in the old town, in a nice quiet street, it was great to stroll out of the hotel to great restaurants, the castle, and other fantastic sights so close by. Our room at Constans was huge, with a big bathroom (shower & bath), which were very clean & well presented. The bath & shower products supplied by the hotel were very nice also. The staff were friendly and more than happy to help with anything we wanted to know about Prague. The breakfast was lovely. We will definitely be returning to Prague, and would only stay at Constans Hotel, which contributed to making our time in Prague so very special.
